Enum Class KeyUsage

java.lang.Object
java.lang.Enum<KeyUsage>
zeroecho.pkix.KeyUsage
All Implemented Interfaces:
Serializable, Comparable<KeyUsage>, Constable
public enum KeyUsage extends Enum<KeyUsage>
The X.509 KeyUsage bits (RFC 5280, 4.2.1.3), in the standard bit order.

This enum is the typed, JCA-friendly counterpart of the boolean-array key-usage representation returned by X509Certificate.getKeyUsage(): the ordinal of each constant equals its DER bit position.

  • Method Details

    • values

      public static KeyUsage[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static KeyUsage valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • bit

      public int bit()
      Returns the DER bit position of this usage (equal to the ordinal).
      Returns:
      the standard bit position
